> the food that's most pushed in modern western countries is full of sugars and carbohydrates.

Starting a ketogenic diet really made this frighteningly apparent to me. I had never really looked at carb or sugar counts in foods before. I now have to make sure to have my own snacks with me or nearby if I'm going somewhere other than home for more than a few hours. It's surprisingly hard to find a quick bite that isn't primarily composed of carbs or doesn't have added sugar.
